Custom service is not displayed when Notification characteristic ist added

[Kampi]

I´m using the BLE app (v4.0.4) for creating a simple testing server with one test service. This test service should contain three characteristic

• Write
• Read
• Notification

The service is displayed correctly in the Connection Map by using these settings for the Notification Service:

And it isn´t displayed when enabling Notify

I also get the following message

13:59:13.887    Failed to set services
13:59:13.887    Expected Array or iterable object of values: 0
13:59:21.513    Failed to set services
13:59:21.513    Error occurred adding characteristic.

Is this a bug or I´m using the app wrong?

Hi. When adding a notify property to the characteristic, the setup expects a CCCD descriptor to be present. The descriptor needs to be added manually, as a child of the characteristic. I suspect that is the problem here.

Hi @bihanssen

thanks. That solves the issue.
